HELP NEEDED! - Turbo stuck in safe mode?

[Veilside Turbo]

Hopefully someone can help me with this problem.

My MR2 Turbo has started boosting as if it is stuck in safe mode. It only "releases" it to normal boost every now and then.

Anyone got any ideas what can be causing this?

Thanks,
Simon

Check for error codes, then fill up with optimax and reset the ecu.

How do I check for error codes? I've read about it before on the old forum but I can't remember. Do I need any special kit?

Also how do I reset the ecu?

Many Thanks!

checking the ecu isn't tricky, and I'm afraid you do need some special equipment. A paper clip. This needs putting into the diagnostics port in the engine bay, but which ports I can't remember, sorry. Need the how-to from the old site. Someone else should know and post shortly!......

Resetting the ecu is no probs, fill up with juice and stop on a lay by on a dual carriage way or something. open the hood and lid, pull out all the fuses that say EFI or ECU, think there's 2/3 in the front and 1 or 2 in the back. Leave them for a mo, plug back in, start her up and give it some stick. That should fix it. But I think you should do the error code check first so you know what was making the problem in the first place, as it may just happen again.

Mr Veilside,

It could be that your running in safe mode because its colder than 4c. Rev 1 and 2 tubbys ECU limit boost in these conditions. You can get rid of it though with a FCD and grainger valve!

Well I couldn't wait for someone to tell me the error codes so I've just reset the ECU (by taking out the EFI fuse) and took it for a blast. Seems to have done the trick, full boost (0.7 bar) WooHoo!!! The boost seems to be spooling up quicker than before too !?!?

I have an FCD and grainger valve but I'm gonna run it like this for a while before I fit it. If the boost drops again I'll try the error codes.

Thanks for the help guys. It is very appreciated!

All the best,
Simon
